Research Project: Developing Sustainable 'IN-ROW' Management Practices for Weed Management and Soil Nitrogen Retention

Location: Crops Pathology and Genetics Research

Project Number: 2032-21220-006-02-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Apr 15, 2011
End Date: Apr 15, 2014

Develop alternative "in-row" weed management practices that both provide effective weed management, do not negatively impact grapevine growth and juice, and improve soil nitrogen (N) retention by minimizing inorganic N leaching and nitrous oxide (N2O) emissions.

Establish three 'in-row' weed management practices: 1)a standard herbicide application; 2)an under-the-vine cover crop, and 3)furrow cultivation with compost. We will focus on surveying changes in both weed seedbank and weed community compostion, measure annual soil N leaching and N2O emissions, and address peak periods of N2O loss during fertigation. This project is part of GRACEnet, a national network of USDA/ARS researchers contributing data from studies on land use and greenhouse gas emissions to develop biogeochemical models and best management practices to minimize N loss from agricultural systems.
